Caffeine
Interpretation
The average doubling time for the YJL133C-A (C2) gene in standard conditions was 89.5 minutes. Under caffeine stress, the average doubling time was 134 minutes. That is a 49.7% increase in doubling time which means that cell growth was negatively affected (slowed down) by this type of stress.
Ethanol
YJL133C-A's line lies in the middle of the overall growth curve. The doubling time is 67.78. These cells went not affected but the Ethanol.
UV Light
The plate with the modified yeast that was not exposed to UV had approximately 5% fewer colonies than the wild-type plate that was not exposed to UV. This shows that the knock-out strain of yeast is expected to be less viable compared to wild-type yeast in the absence of stressors.
The two trial plates were pretty similar in colony count. The average of the two was 10 colonies.
The plate with wild-type yeast that was exposed to UV had 11 colonies.
There was no significant difference in colony count between the modified yeast and wild-type yeast that was exposed to UV.
As there was no significant difference between the wild-type yeast exposed to UV and the trial strains, we can conclude that the gene is not used in the defense against UV damage nor the repair of UV damage in yeast.
Hydrogen Peroxide
This is the link to the protocol page: UW-Stout/Hydrogen Peroxide FA22.
The doubling time for YJL133C-A under the stress of hydrogen peroxide is 306 minutes whereas without stress it was only 206 minutes. As shown in the chart above, the optical density of the YJL133C-A is very similar to that of the wild type yeast. The BY4375 under stress had a 598 minute doubling time and with no stress there was a 229 minute doubling time. Even though the stress placed on the YJL133C-A yeast, resulted in an increased doubling time, this was consistent with the wild type yeast.

UW Stout/FA 2022 Glycerol Media
Introduction
Following the UW-Stout/Glycerol FA22 protocol, 5 knockout strains of yeast cell were tortured within a glycerol media solution.
Results
The following doubling times were calculated:
- Glycerol Trial 1: NA
- Negative Control Trial 1: 163 min
- Glycerol Trial 2: 565 min
- Negative Control Trial 2: 211 min
- Glycerol Trial 3: NA
- Negative Control Trial 3: 236 min
Analysis/Conclusion
Trial 1 and trial 3 of the glycerol torture experiment performed on the knockout on the YJL133C-A in yeast did not look incredibly promising- it is hard to rely on these results and draw any conclusions. The main pattern that seems to be apparent is that the yeast is not reproducing at a consistent rate when grown in glycerol without this gene functioning. A number of different factors could have gone wrong for these results to turn out this way, so it is hard to tell what happened! Disregarding trial 1 and trial 3, the data in trial 3 seemed promising! It is clear that the yeast was growing at a much slower rate, with less than half of a doubling time than what appeared in the negative control. I would definitely say that growing yeast in a glycerol media without YJL133C-A functioning puts a significant amount of stress on the organism.
UW Stout/FA 2022 Bud Scars
Cells that had the gene YJL133C-A had an average of 1.06 scars per cell. Out of 100 cells counted, 106 bud scars were counted. The wild yeast BY4735 had an average of 2.46 bud scars per cell (100 cells counted, 246 bud scars). This indicates that the knocked-out gene significantly slowed down the reproduction rate of these cells.
